Wikipedia Article Summary (CRA Agent)

Choose this endpoint when you need a concise, human-readable overview of a topic sourced from Wikipedia, especially when you want a lightweight summary (not the full article text) plus an image and freshness date. Prefer the full-text sibling endpoint when you need up to 20,000 characters for LLM context. This endpoint is ideal for enriching UI cards, agent briefings, or quick lookups where brevity and speed matter.

• Article title not found on Wikipedia — returns an error or empty result
• Invalid or unsupported language code — falls back to English or returns an error
• Disambiguation pages may not return a clean summary
• Rate limit or payment failure via x402 protocol — request rejected
